Solve the system of equations. y=x+5 y=x2+5x−7 enter your answers in the boxes. 4 5 6 7

(2, 7) or (-6, 1)

Step-by-step explanation:

We are given two equations:

; and

Since y is the subject for both the equations so we can put the values of y equal to each other to get:

Factorizing the expression to get:

Putting x = 2 and x = -6 in any of the equations to get the values of y:

and

Therefore, solution to these equation is (2, 7) or (-6, 1).

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
